Publication number: 20120304859Abstract: The invention relates to a process and a device for carrying out a gas scrubbing, in which gas is conducted from bottom to top and scrubbing medium is conducted from top to bottom through a scrubbing column (T). In the scrubbing column (T) at least two scrubbing sections (WS1 and WS2) are arranged one above the other, of which the upper is restricted downwards by a chimney tray (K). From the chimney tray (K) at least some of the scrubbing medium loaded in the upper scrubbing section (WS2) is taken off at a take-off point (A) provided in the region of the chimney tray (K) and introduced as scrubbing medium into the lower scrubbing section (WS1) at an introduction point (E) provided in the region of the lower scrubbing section (WS1). A heat-exchange appliance (6) is connected in series in the direction of flow downstream of the take-off point (A) and upstream of the introduction point (E).Type: ApplicationFiled: November 4, 2010Publication date: December 6, 2012Applicant: LINDE AKTIENGESELLSCHAFTInventors: Dieter Mihailowitsch, Eckard Steinmetz

Patent number: 8308144Abstract: The present invention provides a diaphragm carburetor wherein heat transferred from the engine to the carburetor through the insulator is reduced to lower the temperature of the carburetor unit and reduce the occurrence of bubbles in the fuel. The carburetor of the present invention is a diaphragm carburetor in which a fuel channel that extends from a pump chamber of the carburetor to a constant-pressure fuel chamber is divided into two branches to form one branch as a main fuel channel connected to the constant-pressure fuel chamber, and the other branch as a fuel circulation channel for passing the fuel through the body side surface of the carburetor on the insulator side, or the body side surface of the insulator on the carburetor side, causing the fuel to make a circuit around the carburetor, and returning the fuel to the fuel tank.Type: GrantFiled: November 18, 2009Date of Patent: November 13, 2012Assignee: Zama Japan Kabushiki KaishaInventor: Tamotsu Saito

Publication number: 20120217662Abstract: A cooling tower for evaporating water from a brine solution is provided and may include a housing having an air inlet and a brine inlet. The cooling tower may also include a heat-exchange assembly having a heat-exchange media that suspends the brine solution and at least one nozzle in fluid communication with the brine inlet. The at least one nozzle may receive the brine solution from the brine inlet and may transfer the brine solution from the brine inlet to the heat-exchange media to allow the heat-exchange media to transfer moisture from the brine solution to air received from the air inlet to reduce the moisture content of the brine solution.Type: ApplicationFiled: May 7, 2012Publication date: August 30, 2012Applicant: MITEK HOLDINGS, INC.Inventors: Kelly D.

Publication number: 20120153514Abstract: Condensable vapors such as carbon dioxide are separated from light gases in a process stream. The systems and methods employ a direct exchange heat exchanger to desublimate the condensable vapors from the process stream. The condensable vapors are condensed by directly contacting a heat exchange liquid in the direct contact heat exchanger while the uncondensed light gases from the process stream form a separated light-gas stream. The separated light-gas stream can be used in a recuperative heat exchanger to cool the process stream.Type: ApplicationFiled: November 21, 2011Publication date: June 21, 2012Applicant: Brigham Young UniversityInventors: Larry L.

Patent number: 8167282Abstract: A method of fabricating a glass body that includes a multiplicity of constituents, at least one of which is a dopant (e.g., a rare-earth element) having a low vapor pressure (LVP) precursor includes the steps of: (a) generating an aerosol from the LVP precursor; (b) separately generating vapors of the other constituents; (c) convecting the aerosol and vapors to deposition system including a substrate; and (d) forming at least one doped layer on a surface of the substrate. In one embodiment, the method also includes filtering the aerosol so as to remove aerosol particles outside of a particular range of sizes. Also described is a unique aerosol generator that is particularly useful in generating aerosols of rare-earth dopants. Particular embodiments directed to the fabrication of Yb-doped optical fibers are described.Type: GrantFiled: November 3, 2011Date of Patent: May 1, 2012Assignee: OFS Fitel, LLCInventors: Anthony Michael DeSantolo, Robert Scott Windeler

Patent number: 8132793Abstract: An apparatus for atomizing a precursor liquid for vapor generation and thin film deposition on a substrate. The precursor liquid is atomized by a carrier gas to form a droplet aerosol composed of small precursor liquid droplets suspended in the carrier gas. The droplet aerosol is then heated to form vapor, producing a gas/vapor mixture that can be introduced into a deposition chamber to form thin films on a substrate. The liquid is introduced into the atomizing apparatus in such a manner as to avoid excessive heating that can occur or lead to the formation of undesirable by-products due to material degradation as result of thermal decomposition. The apparatus is particularly suited for vaporizing high molecular weight substances with a low vapor pressure that requires a high vaporization temperature for the liquid to vaporize. The apparatus can also be used to vaporize solid precursors dissolved in a solvent for vaporization.Type: GrantFiled: September 11, 2009Date of Patent: March 13, 2012Assignee: MSP CorporationInventor: Benjamin Y.

Publication number: 20110296994Abstract: The present invention relates to reactor vessels such as absorbing or stripping columns that are suitable for capturing carbon dioxide from flue gas streams of fossil fuel fired powered stations such as coal fired power stations generating 100 to 500 MW. The side walls of the reactors are made of concrete or structural ceramics that are preferrably steel reinforced. The reactors are on a sufficiently large scale such that a flue gas stream in the order of at least 1,000 t/hr and normally greater than 2,000 or 3,000 t/hr can be scrubbed of carbon dioxide in a single absorption column and then recovered in a stripping column. The absorbing and stripping columns may be free standing structures or, alternatively, the absorbing column may be located at least partially within the stripping column.Type: ApplicationFiled: May 12, 2008Publication date: December 8, 2011Inventors: Geoff Stevens, Barry Hooper, Craig Dugan, Paul Anthony Webley

Patent number: 8038129Abstract: Circulating air is cooled by heat exchange with adiabatically cooled process air. To this end, a first heat exchanging device is fed with circulating air and the process air. The heat exchanging device contains a humidifying device used to spray water into the process air. In this way, the process air is adiabatically cooled and the corresponding cooling is carried out by heat exchange with the circulating air. Before entering the first heat exchanging device and before leaving same, the process air is guided through a second heat exchanging device in which the cooled process air first extracts heat from the uncooled process air. This increases the cooling performance of the device.Type: GrantFiled: July 6, 2009Date of Patent: October 18, 2011Assignee: Hovalwerk AGInventors: Edgar Beck, Christoph Steinhäusler
